ASTM B564 Alloy 400 UNS N04400 threaded WN LWN SO SW BLIND flange

 UNS Number:UNS N04400


Other common names:  Monel 400, Alloy 400, 2.4360, NS111

 

Monel400 is a corrosion-resistant alloy with the largest amount, the most versatile and excellent comprehensive performance. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, and also has excellent corrosion resistance to hot concentrated lye. At the same time, it is resistant to corrosion from neutral solutions, water, seawater, air, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracks and has good cutting performance.
